Activating RBL in Exim Configuration Manager?

Hi! I was thinking in activating this RBL: bl.spamcop.net RBL: zen.spamhaus.org in Home "Service Configuration "Exim Configuration Manager If I do it and one day my own IP is listed in one of those blacklists... what would happen? If someone inside my server sends an email to an account hosted in my server (or for example to himself), it will receive an bounced email? I should add my IPs in "Whitelist: IP addresses that should not be checked against RBLs"? Thanks, Francisco
